An American filmmaker recorded the images and voices of aging atomic-bomb survivors so they could pass down their memories to younger generations and make them think more about nuclear weapons.

Titled "Hibakusha, Our Life to Live," the film describes the lives of Japanese and Korean hibakusha through a mixture of interviews, as well as a fictional drama about a preteen Japanese girl who learns about the 1945 bombings from Eiji Nakanishi, a real hibakusha who was exposed to the bombing in Hiroshima at age 3.

"Once they (the survivors) are gone, all will be secondhand stories, not firsthand . . . So I think their memories must be kept alive in as many ways as possible," David Rothauser said in a recent interview in Tokyo.
